The real star here is the late aerial photographer James Freeman, whose breathtaking helicopter shots of Mayan and Aztec ruins at sunrise and sunset won an Academy Award for this film in 1971. Although the English version was narrated by Orson Welles, the Spanish version, narrated by Ricardo Montalban, is in better keeping with the ethnic aspect of the film, and no knowledge of Spanish is needed to appreciate his dramatic impact. Don't be put off by the heroic musical score: this film is memorable, the last word on spectacular ruin cinematography. Director Robert Amram has, according to at least one report, vanished south of the border. Freeman was killed while scouting a location for a commercial sponsored by Eastman Kodak.
